Thanks for the compliments, its a real encouragment to hear feedback from fellow modelers.
Here's a few more shots of it's construction.
This is the floor, I epoxied the track with ties to the styrene floor, thae added 1/4" square styrene tubing around the edges as a dam. The floor was then poured using soupy hydrocal so I would have a 'concrete' looking floor.
Walls just after first paint color, the entire enginehouse was constructed out of styrene so I had my work cut out to make styrene look like wood. I scribed the backside of the siding to make it look like individual boards, then added the framing on top, using scale lumber styrene strip.
the basic structure is assembled and I masked all the windows, doors and roof so I could airbrush it in Floquil tuscan.
